BOX FOR THE STOP-COCKi-S OF SERVICE-PPEIS.

SPECIFICATION forming part of Letters Patent N o. 349,567, dated September 21, 1886.

Application filed April 6, 1866. Serial No. 198,041. (No model.)

To all whom, it may concern:

Be inlmownniat I, JOHN v. CLARKE, a cirizen of the United States, and a resident of Watertown, in the county of Jefferson and State of New York, have invented certain new and useful Improvements in Boxes for the Stop-Cocks of Service-Pipes; and Ido hereby declare that the following is a full, clear and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is `a vertical sectional view showing the application of-my improved box for the stop-cock of -a service-pipe; and Fig. 2 is a similar view taken at a right angle to the section in Fig. 1, and showing a slight modi fication in the outer tube.

Similarletters of reference indicate corresponding parts in both the figures.

My invention has relation to boxes or tubes for the stopfcoeks of water or gasservice-pipes which pass from the surface ofthe ground to a pipe below the ground, having a stop-cock for the purpose of cutting off the supply passing through the pipe; and it consists in theimproved construction and combination of parts of such a box or tube, as hereinafter more full y' described and claimed.

In theaccompanying drawings, the letter A indicates the stop-cocl;,wliich is provided with a screw-threaded neck, G, upon its upperside, and which is provided with the head or handle K of the plug in the cock,by means of which handle the plug is turned. An outer tube, C, extends from the surface of the `ground down to the cock, and the upper end of the tube is provided with aremovable screw-cap, B, and a shorter pipe, D, having a packing-ring, F, of rubber' or similar elastic material around its upper end, iits within the outer tube and has Aits lower female screw-threaded end secured upon the screw-threaded shoulder or neck of the stop-cock. The shorter inner tube cxtends as far as the water in the ground is liable to rise in wet Weather, and it will be seen that the inner tube being screwed tothe stopcock no water can enter at the lower end of the tube, and the upper end of the tube is above the level to which the water in the ground is liable to rise, and at the same time the upper end of the tube is sliding with its packing within the tube, so that no water can possibly enter, even if the water rises above theend: of the inner tube. The inner tube sliding within the outer tube will allow the latter to move up or down in the ground, as it isliable to do during frosty weather,without injuring the inner tube or the cock, and the tubes will always keep the head of the plug free from dirt or ac cuinulated water, so that it may always be reached with a key or wrench and turned.

Forthe purpose of preventing the outer tube from turning,the lower end ofthesame may be provided with a downwardly-extending lip, E, at one side, which lip will bea-r against theside of the cock and prevent the tube from turning when the screw-cap is secured upon its upper end or removed. If the inner tube is sufriciently high to prevent any possibility of the water entering above it, the packing may be dispensed with at the upper end of the tube.

Having thus described my invention, Iclaim and desire to secure by Letters Patent of the United States- The combination, with a service-pipe stopcock having a tube secured to the upper side,

extending upwardly therefrom, of-an adjustable capped tube provided at itslower end with a downwardly-projecting lip, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

JOHN V. CLARKE.
